Divide or multiply the output by a constant to expand or contract the graph in the y direction.
What does f 2x do to a graph?
2f (x) is stretched by a factor of 2 in the y direction, and f (x) is contracted by a factor of 2 in the y direction (or stretched by a factor of ).
The y = f (x), y = 2f (x), and y = x graphs are shown here.
This is the difference quotient:
f (x + h) - f(x ) /h
quotient of difference
and f(x) = x3; thus, the difference quotient for this function is
(x + h)³ - x³ / h
quotient of difference.
The numerator can now be simplified by expanding (x + h)3 as (x + h)2(x + h), however I advise factoring (x + h)3 - x3 as a difference of cubes.

The Singh family ordered a large pizza with a diameter of 16 inches for dinner. If one of the members of the family ate one eighth of the pizza, how many square inches of pizza are remaining? Use 3.14 for π.
200.96 square inches
175.84 square inches
100.48 square inches
25.12 square inches
Answer: D
Step-by-step explanation: 25.12
Answer: The actual answer is (175.84 square inches)
Step-by-step explanation:
First, find the area of the pizza.
You need to use the formula for area of a circle: A = πr^2
or in words, the area of a circle is equal to pi times radius to the second power.
So find the radius which is half the diameter.
The diameter is 16 inches, so the radius is 8 inches.
Now raise 8 to the second power, meaning that you need to times 8 by 8
(8 * 8 = 64) Now you times 64 by pi or 3.14. (64 * 3.14 = 200.96)
That is the area of the entire pizza.
But you still need to find how many square inches are left after 1/8 is eaten.
If 1/8 is eaten, then that means the pizza is divided into eighths.
Take 200.96 and divided that by 8 to find how much the individual pieces are.
200.96/8 = 25.12
But you need to find what is left is the pizza, so times 25.12 by 7 because that is how many pieces are left. 25.12 * 7 = 175.84

elijah used 3/4 of the memory on his cell phone memory card if the memory card can hold 32 gigabytes how many gigabytes did elijah used
Elijah used 24 gigabytes memory on his cell.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Elijah used 3/4 of the memory on his cell phone memory card.
And, The memory card can hold 32 gigabytes.
Now,
Since, The memory card can hold 32 gigabytes.
And, She used 3/4 of the memory on his cell phone memory card.
Hence. The used memory = 3/4 of 32
= 3/4 × 32
= 3 × 8
= 24 gigabytes
Thus, Elijah used 24 gigabytes memory on his cell.

Identify two segments that are marked congruent to each other on the
diagram below. (Diagram is not to scale.)
The two congruent segments in the figure are LJ and LI.
What is congruency?
The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.
An included angle is found between two sides that are under consideration.
Thus, two triangles having two pairs of corresponding sides and one pair of corresponding angles that are congruent to each other is not enough justification for proving that the two triangles are congruent based on the SAS Congruence Theorem.
In the figure, the two segments marked are LI and LJ these two segments are congruent to each other.
Congruency means the shape and the size of the segments will be equal to each other.
Hence, the two congruent segments in the figure are LJ and LI.

Calculate the state income tax owned on a 40,000 per year salary
Answer:
The state income tax to be paid will be $ 2,300.
Step-by-step explanation:
Given that an annual salary of $ 40,000 pays a state income tax of 5.75% of said value, to determine the total amount of tax to be paid, the following calculation must be made:
40,000 x 5.75 / 100 = X
230,000 / 100 = X
2,300 = X
Therefore, the state income tax to be paid will be $ 2,300.

o-28(x + 2) = (y - 1)2

The equation (y + 1)² = -12(x - 2) represents the given parabola.
What is a parabola?
A parabola is a U-shaped plane curve. It is assumed to be mirror symmetrical. A parabola is produced by the intersection of a right circular cone and a plane parallel to the cone.
The vertex is at (-2, 1) and the directrix is x = 5.
Therefore, the vertex of the given parabola is at 2nd quadrant.
Again, the directrix is also parallel to the y-axis.
As a result, the parabola will open towards the left.
The general form of a parabola is (y - k)² = 4a(x - h)
Here, h and k are x and y coordinates respectively of the vertex.
Now, the coordinates of the focus are (h + a , k) and the directrix is at x = h − a.
Therefore, h - a = 5 (as, x =5)
⇒ 2 - a = 5
⇒ a = -3
Therefore, the equation of the parabola is (y − k)² = 4a(x − h)
⇒ [y - (-1)]² = 4(- 3)(x - 2)
⇒ (y + 1)² = -12(x - 2)
The equation of the parabola that has a vertex (2 , -1) and a directrix
of x = 5 is (y + 1)² = -12(x - 2)

In a survey of 1,000 women aged 22 to 35 who work full time, 545 indicated that they would be willing to give up some personal time in order to make more money. The sample was selected in a way that was designed to produce a sample that was representative of women in the targeted age group.
a. Do the sample data provide convincing evidence that the majority of women age 22 to 35 who work full-time would be willing to give up some personal time for more money? Test the relevant hypotheses using α = .01.
b. Would it be reasonable to generalize the conclusion from Part (a) to all working women? Explain why or why not.
Answer:
Yes, there is convincing evidence that the majority of women age 22 to 35 who work full-time would be willing to give up some personal time for more money.
No ;
Step-by-step explanation:
n = 1000
x = 545
Phat = x / n = 545/1000 = 0.545
H0: p ≤ 0.5
H1: μ > 0.5
The test statistic :
(phat - p0) ÷ √(p(1 - P0) / n)
Test statistic :
(0.545 - 0.5) ÷ √(0.5(0.5) / 1000)
0.045 / 0.0158113
Test statistic = 2.846
α = 0.01
Decison :
Reject H0 ; if Pvalue < α
Using the Pvalue from Test statistic (Z) calculator :
Pvalue = 0.002214
With Pvalue < α ; We reject H0 and conclude that there is convincing evidence that the majority of women age 22 to 35 who work full-time would be willing to give up some personal time for more money.
No, making generalization about all women would not be reasonable as the data employed for the research mainly focuses on a particular
The power generation plant of a ship is outfitted with two identical diesel-generator sets. One single set running stand-alone can meet the full power requirement of the vessel. The engine of each set has a malfunction probability of 25% and the generator of 10%. In case one set breaks down there is a 50% probability of it being repaired but it will run again only if repaired and its subsystems do not further malfunction upon startup. Calculate the probability of an electric power outage shipboard.
Answer:
probability of an electric power outage shipboard is 0.075 or 7.5 %
Step-by-step explanation:
Given the data in the question;
Probability of engine malfunction = 25% = 0.25
Probability of generator malfunction = 10% = 0.1
Probability of generator being repaired = 50% = 0.5
probability of an electric power outage shipboard = ?
To get the probability of an electric power outage shipboard, we use the expression;
probability of an electric power outage = 2[tex]_c_1[/tex] × p( Probability of generator malfunction ) × p( Probability of generator being repaired ) × ( 1 - p( Probability of engine malfunction ) )
so we substitute in our given values;
probability of an electric power outage = 2 × 0.1 × 0.5 × ( 1 - 0.25 )
probability of an electric power outage = 2 × 0.1 × 0.5 × 0.75
probability of an electric power outage = 0.075 or 7.5 %
